qemu discuss - May 2007 - Updates to Downloads, and other How-to''s

I have posted current tarball of the CVS code base with 2 patches for Compilling
QEMU
on a 64-bit system (automagically), as well as a current tree for KQEMU and
libSDL-1.2.12
in the download section.

I have also posted some proof of concept files and scripts for using the TAP
interface with
Solaris and QEMU, for both TAP (local host access) and BRIDGE (local net
access), along
with an "Understanding Networking in a QEMU Guest" to help guide your
configuration
for the client.

Comments welcome.

Cool!

hello,
i''m trying to compile qemu on Solaris 10 U2 on ultra 20 (amd64), but
configure failed:
caiman-henry% ./configure --prefix=/tmp/qemu

ERROR: QEMU requires SDL or Cocoa for graphical output
To build QEMU without graphical output configure with --disable-gfx-check
Note that this will disable all output from the virtual graphics card.

but SDL is here, i compiled it as explained on web site:
caiman-henry% which sdl-config                                                 
/opt/local/bin/amd64/sdl-config
caiman-henry% sdl-config --version
1.2.12

Anybody can help? The same thing works on Nevada b56 without compiling SDL (SDL
from blastwave, 32 bits)

thanks,

gerard

This is typically because the version of sdl-config configure found
didn''t
compile the test right.

What''s your path look like when you invoke configure?

if /opt/local/bin/amd64 isn''t before /opt/local/bin (or /opt/csw/bin),
then that is
probalby why it failed, because it caught a 32-bit libSDL when trying to
compile it on 64-bit.

I was not aware that Qemu can be built on 64-bit system as a 32-bit binary 
using blastwave''s gcc and using a 32-bit libSDL, but it''s not
unreasonable to
expect.  I have some patches that have not been integrated yet
for compiling 32-bit QEMU on a 64-bit host, but we ran into a problem with 
gcc from /usr/sfw/bin failing the compile (which has been documented on the
site)  and I don''t have blastwave''s gcc on that S10U2 system. 
I''ll see if I can
do something about testing that...

yes, nevada b56 was installed on a laptop, so it is 32-bit host

I''m trying to understand why configure failed, so i added some prints
in configure to see the values that cause tests to failed. I''m not very
confident with shell scripts, here is what i got:

I don''t understand why sdl test fail, how test is done? there is no
config.log as in other foss

On this machine, uname is:
